IF Origin characters are going to have additional voiced dialogue that is shall we say "standard" i.e. not JUST used in specific Origin character moments, then the solution would be to have voice as an option during character creation and allow us to decide if we want our custom character to sound like one of the Origin characters or simply leave blank. What that does to animation though I don't know.
But as one can see, there is an equal divide here between voiced vs non voiced full stop. It's totally subjective as to what is considered good vs not.
